Superinfection: Colds, or upper respiratory infections, are most commonly cause by viral infections which resolve on their own in 3-7 days. Viral infections do NOT respond to antibiotics. However, when your immune system is taxed by fighting the viral infection, bacterial infections can set in. Symptoms that do not improve within a few days, worsening symptoms, new fever or chest pain warrants a doctor visit.
